Defined in header <bitset>
​template< size_t N > class bitset;​

Bitsets give the programmer a set of bits as a data structure. Bitsets can be manipulated by various binary operators such as logical AND, OR, and so on.

The size of a C++ bitset is fixed at compile-time, and the size is the template parameter to the bitset.

Contents 1 Member functions 1.1 Element access 1.2 Capacity 1.3 Modifiers 1.4 Conversions Member functions
(constructor)	constructs the bitset (public member function)
operator=	assigns the contents (public member function)
operator== operator!=	compares the contents (public member function)
Element access
operator[]	accesses specific bit (public member function)
test	accesses specific bit (public member function)
all	checks if all bits are set to ​true​ (public member function)
any	checks if any of the bits are set to ​true​ (public member function)
none	checks if no bits are set to ​true​ (public member function)
count	returns the number of bits set to ​true​ (public member function)
Capacity
size	returns the size number of bits that the bitset can hold (public member function)
Modifiers
operator&= operator|= operator^= operator~	performs binary AND, OR, XOR and NOT (public member function)
operator<<= operator>>= operator<< operator>>	performs binary shift left and shift right (public member function)
set	sets bits to ​true​ or given value (public member function)
reset	sets bits to ​false​ (public member function)
flip	toggles the values of bits (public member function)
Conversions
to_string	returns a string representation of the data (public member function)
to_ulong	returns a long integer representation of the data (public member function)
to_ullong (C++0x)	returns a long long integer representation of the data (public member function)
